Receiver Designing of the X-Band High Spatial Resolution Radiometer

摘要

The research of the X-Band High Spatial Resolution Radiometer (X-Band HSRPR) is trying to enhance the spatial resolution by the synthetic aperture antenna. Its sensitive of the temperature measurement is 1.5K and the spatial resolution is 2~0. The receiver includes 8 channels. Every channel compose 4 main parts: (1) high frequency components, (2) mid frequency amplifiers, (3) power dividers, (4) correlation detectors, and 2 supplementary parts: (1) local oscillator and (2) noise source. The article introduces the designing of the receiver and the characters designing of the components in the channels.
